This talk will cover how gcc and clang/LLVM compilers can boost the Embedded Linux Development by optimizing for size and performance on constrained systems. It will also cover specific commandline options that are available for tuning the programs for power/performance/size optimizations and how they impact each other. It will also discuss how can we get better code by helping the compilers by writing "friendly" code. Primarily it will focus on C but will also cover C++. Since we have multiple architectures supporting Embedded Linux, we will also discuss architecture specific tunings and optimizations that can be taken advantage.
